I think people making money off 3d prints are not people who have had to deal with this before.
Ask any artist or creator in any other medium and you’ll get a resigned sigh and “it is what it is” but I’ve noticed the 3d printing community is way more aggressive about percieved copyright infringement which always has the extra layer of irony when they use AI for images, their avatar/profile pic and/or models generated entirely by AI.
I’m not saying folk here don’t have the right to be upset but you’re just one person against the entirety of scammers and tracers and copiers etc.
Do basic damage control, report what needs to be reported but at the end of the day its just how it is.
There is little else you can do because even if you go as far as to change the law to add more protections its still only your country.
Again; ask any artist how people seem to befriend you and then coincidentally mention that their birthday is coming up and then stop being your friend after. People be rude and scummy. It is what it is.
